Testosterone replacement therapy by testosterone ointment relieves lower urinary tract symptoms in late onset hypogonadism patients

Methods. The Aging Male Symptom (AMS) scale, Medical Outcomes Study (MOS) 36-Item Short-Form Health Survey (SF-36), International Index of Erectile Function (IIEF-5) and the International Prostate Symptom Score (IPSS) were obtained from patients with LOH. A total of 41 patients with LOH have been treated with TRT using 6 mg/day of GL for 3 months. Serum free testosterone levels (FT) and these four scores were compared before and after TRT. Results. Serum FT levels and the scores for the four parameters of AMS, six of eight domains in SF-36, IIEF-5 and total IPSS improved significantly after 3 months TRT. In addition, all IPSS domains also improved significantly, and voiding disturbance seems to have improved more than storage disturbance (P = 0.0280 vs. 0.0483). Conclusion. TRT by administration of GL is considered to be effective in the improvement of not only ED and LOH symptoms, but also LUTS (especially voiding disturbance) of patients with LOH.
